摘　　要：【目的】明确寄生草地贪夜蛾(Spodoptera frugiperda)的甲腹茧蜂(Chelonus sp.)雄成虫触角和胸足感器的种类、形态和分布。【方法】利用扫描电镜技术系统观察寄生草地贪夜蛾的甲腹茧蜂雄成虫触角和胸足(前、中、后足)感器的超微结构。【结果】甲腹茧蜂雄成虫触角和胸足共分布有5种感器,分别为毛形感器(3种亚型Ⅰ~Ⅲ)、板形感器、刺形感器、锥形感器(4种亚型Ⅰ~Ⅳ)和钟形感器。寄生草地贪夜蛾的甲腹茧蜂雄成虫触角和胸足上均有毛形感器和锥形感器分布,毛形感器数量最多且分布最广,板形感器仅分布于触角鞭节,钟形感器仅分布于中足腿节。【结论】寄生草地贪夜蛾的甲腹茧蜂雄成虫触角和胸足感器类型丰富,但不同类型感器的分布部位不同,可为探讨草地贪夜蛾寄生蜂的行为机制提供理论依据。[Purpose]To observe the types,morphology and distribution of sensilla on antenna and thoracic leg on male adult of parasitoid of Chelonus sp.of Spodoptera frugiperda.[Methods]The ultrastructure of sensilla on antenna and thoracic leg(propodeum,mesopdium and metapodium)was observed with scanning electron microscopy.[Results]Five kinds of sensilla on male adult of parasitoid of Chelonus sp.of S.frugiperda,including sensilla trichodea(three subtype Ⅰ-Ⅲ),sensilla placodea,sensilla chaetica,sensilla basiconica(four subtype Ⅰ-Ⅳ)and sensillum campaniform were observed.Sensilla trichode and sensilla basiconica were observed both antenna and thoracic leg.Most of sensilla trichoidea were most widely distributed on parasitoid of Chelonus sp.of S.frugiperda.Sensilla placodea was only found on flagellum of antenna.Sensillum campaniform was only found on femur of mesopdium.[Conclusion]There are various sensilla types of antennae and thoracic leg on male adult of Chelonus sp.,but the distribution of different sensillaries is different,which provides a theoretical basis for the study of the behavior mechanism of the parasitoid wasp of S.frugiperda.
